Following testing of blood for HCV, the number of new infections has dropped remarkably. The problem is chronic HCV and the question is can we bring down incidence of any disease low enough that it no longer is a problem? isnt that eradication and similar things are happening with HIV in South Africa. The prevalence of the disease is stabilised because the number of deaths equals the number of new infections.
Can we model how much we need to decrease infection to prevent a disease being a public health problem?
